| Outline of Final Research Achievements |
I used data collected from a nationwide five-wave panel survey in Japan, and examined two causal relationships: (1) high-intensity caregiving and mental health of informal caregivers, and (2) high-intensity caregiving and continuation of caregiving. Considering the heterogeneity in high-intensity caregiving among informal caregivers, control function model which allows for heterogeneous treatment effects was used.
This study uncovered three major findings. [1] Caregivers who experienced high-intensity caregiving (20-40 h) tended to continue with it to a greater degree than did caregivers who experienced ultra-high-intensity caregiving (40 h or more). [2] High-intensity caregiving was associated with worse mental health among non-working caregivers, but did not have any effect on the mental health of irregular employees. [3] Non-working caregivers did not tend to continue high-intensity caregiving for more than three years, regardless of co-residential caregiving.
